DRAIN-HEAD,

Specification of Letters Patent.

Patented. Au g. 26, 1913.

Application led February 18, v1913. Serial No. 749,231.

To all whom t mag/concern.'

Be it known that I, JOSEPH F. McPAR- LAND, a citizen of the United States, residing at Dubuque, in the county of Dubuque and- State of Iowa, have 'invented certain new -a-nd useful Improvements in Drain-Heads; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilledin the art to which it apipertairus to malte and use the same.

This invention relates to drain-heads.

An object of the invention is to provide an improved form of drain head to be used in connection with. tileor other drain pipe, for conveying the water from the clay-soils downward through the stratum of clay into the sub-strata of sand or other soil which is more porous than the clay, so as to provide a proper drainage for the clay-soil.

Another object of the invention is to provide a. device of this character in connection with a comparatively shallow well of considerable area, and 'to cover said well so as to prevent the same from being, filledV with earth, so that water may accumulate within the well whence it is conducted downward through the drain pipe or tile.

A further object of the invention isl to` provide a drain-head of this character with an air outlet and with a protecting cap or crown forthe air outlet.

Other objects and advantages vmay be recited hereinafter and in the claims.

In the a'ceompanyin s,r drawings which supplement this specification, Figure l is a vertical sectional view through my inproved drain-head and through the well and drain tile associated therewith. Fig. 2 is a per--A 4spective view of `my improved drain-head and the tile associated therewitlnand, Fig,.- 3 is a fragmental sectional View of the drain head and cap taken on the line 3 3 of Fifr. 1.

Referring'specitically to the drawings, in which similar reference characters indicate the same parts in all of the figures, indicates a hollow cap member and 5` a separate dome shaped crown member. The crown' lmember 5 is provided with a horizontal peripheral flange 10 and has its eentrahupper portion on the inside thickened`v at 15, and flattened to rest upon the top of a shaft 8, preferably composed of superposed tiles. Upwardly projecting from the center of the crown member is a tubular extension '12 having a central' bore 11, which communicates with the interior of the cap member 6. Thecap member rests upon the top of the crown member and 1s provided in its lower edge with openings 13. The thickened portionl.

of the crown member is provided with radial grooves 11 which communicate between the interior of the crown member and theA interior of the shaft S, the latter communieating in anysuitable manner at its lower end with the surroundingearth.

To tix the device in position for operation,

a proper shallow well 7 is dug into the clay stratum and in its .center is b`ored a deepen circular opening,r to receive the lower end of the shaft 8, said .opening extending,r into the more porous earthbclow`the clay stratum. The upper edge 9- of the well forms a shelf f upon which the flange 10 of the -crown is placed, after which the cap G is placed upon the top of the crown, the 'spaces between the top of the tubular extension 12 and -the interior of ,the cap-affording free communi- `cation between 'these two parts. Water in the clayY stratuinvill settlcinto the well and up under the crown, 'and will pass through the grooves 14 into vthe 'center of the shaft, down which it drops and from the. lowerI end of which it pereolates or soalis into the porous earth below." Air in the dome will be forced upwa rd and missing through the `grooves 114. will rise through the tubular-extension 19, passing over the top thereof into the cap, and from the cap out through the"- openings 13. t

It will he. seen that I have provlded an improved form of drain head which is fully capable of attaining the foregoing! objects in a tlmroughlv practical and eliieient manner. I do not limit in v invention to the exact details of eonstructifm,coml'iination and a-rrangement of parts as herewith illustrated and described, but my invention may only be limited by-a reasonable interpretation of the claims. i

1. A drain head consisting of a domeshuped cap having a horizontal peripheral base flange around the bottom edge thereof anda central vertical tubular extension at its top, and an inverted cup-shaped crown seated over the tubular element` communicatin with the interior of the cap and pro- '.vide with' nir outlets below the top of the tubular elemno 2'. In combination` n drain shui-'1 centrally erected in n well, a cap resting upon the top of the man pipe andthe edged-f the wen and having acentral opening communicating vwith the drainshahpthe 'relation of the l'3. Asdiavin head oonsisting .of a dome-- v 1.0l shaped ycover for a well, having an aperture I throughl itsftop', and su'bstantiuily vhemispherioal crown over the aperture ofthe cover,sa1d crown havmg air outlets.

In testimony whereof -I- have signed name tothis specification inthe presence of 15 two subscribing witnesses.
